Description

Automation of video data using Micro SD Card Switching Board {Automation of video data using Micro SD Card Switching Board}

This specification relates to a device for automatically testing black box images, and more specifically, to a black box image testing device using a micro SD card switching board.

As the use of black boxes becomes more popular, driving videos while driving a vehicle are captured and stored through the black box. Additionally, even if the vehicle's engine is turned off, parking images can be captured and saved while parked.

Black boxes need to shoot high-definition images in order to identify objects (vehicle license plates, people, etc.) in the captured images. As a result, the file size of the captured images increases, so the storage capacity of the black box captured images is considerably larger. It is increasing. Accordingly, it is important to check for errors in the storage device (for example, micro SD card, etc.) where the captured images of the black box are stored.

Conventionally, in order to directly check whether there is an error in the video data in the black box, the micro SD card that stores the video is manually removed from the video captured in the black box, and the presence of an error in the video stored in the micro SD card is determined. The video recorded through the black box is inspected by examining it through electronic devices.

However, if there is an error in the video recorded through the black box, there is an error in the black box device itself, an error in the micro SD card itself that stores the recorded video, an electrical connection defect in the micro SD card, or a communication function error. There may be various error factors such as whether there is a problem with the back.

In this case, it is inconvenient for the user to repeatedly remove and install the micro SD card to create various scenario conditions for testing. Accordingly, there is a need to shorten interrupt and test times by improving the black box test environment.
